<3> [140.850285] [drm:wa_list_verify [i915]] *ERROR* rcs0 workaround lost on before reset! (b118=0/0, expected 200040, mask=200040)
Comment 1 Chris Wilson 2018-12-05 15:18:17 UTC
Even more confusing is that it stopped occurring. Still the same machine (icl6).
Comment 2 Chris Wilson 2018-12-05 15:55:25 UTC
Failure in reading; it has failed twice now on iclb3.

Passed on iclb5, iclb6, iclb7 so far. It could just be that one machine... Fits in with the pre-production theory.
Comment 3 Chris Wilson 2018-12-06 08:28:55 UTC
And now it is appearing out of the blue on BAT fi-icl-u3.

That at least appears to have been a bad merge now fixed up by Tvrtko.
Comment 5 Francesco Balestrieri 2018-12-18 11:42:33 UTC
Not seen in 6 days, used to be occurring very frequently. Hopefully fixed but let's keep monitoring it...
Comment 6 Francesco Balestrieri 2019-01-08 09:25:37 UTC
Keeps happening, here is the latest occurrence from 5 days ago:

Comment 7 Francesco Balestrieri 2019-01-08 13:07:41 UTC
Only seen in iclb3 in the past month, but has failed on b1, b7 and b5 before that.
Comment 8 Francesco Balestrieri 2019-01-09 08:25:08 UTC
Mika, could you take a look?
